Using a laboratory experiment with minimal groups, we examined the extent to which the threats of costly punishments affect in-group favouritism behaviour. We studied three types of punishment separately: in-group, out-group, and third-party punishments. In line with previous studies, the...

In this paper we investigate how cognitive ability influences behavior, success and theevolution of play towards Nash equilibrium in repeated strategic interactions. We study behaviorin a p-beauty contest experiment and find striking differences according to cognitiveability: more cognitively...

A person is said to be `trust responsive` if she fulfils trust because she believes the truster trusts her. The experiment we report was designed to test for trust responsiveness and its robustness across payoff structures, and to disentangle it from other possible factors making for...

This paper examines the relationship between norm enforcement and in-group favouritism behaviour.  Using a new two-stage allocation experiment with punishments, we investigate whether in-group favouritism is considered as a social norm in itself or as a violation of a different norm, such as...

In this paper we investigate how cognitive ability and character skills influence behavior, success and the evolution of play towards Nash equilibrium in repeated strategic interactions.  We study behavior in a p-beauty contest experiment and find striking differences according to cognitive...

There has been a dramatic surge in Islamic participation and values since the 1970s.  We propose a theory of the contemporary Islamic revival based upon two forms of relative deprivation - envy and unfulfilled aspirations.  To analyze these motivations, a behavioral model of religion is...

We develop a novel computerized real effort task, based on moving sliders across a screen, to test experimentally whether agents are disappointment averse when they compete in a real effort sequential-move tournament.  Our theory predicts that a disappointment averse agent, who is loss averse...

The exchange between Epstein (2010) and Klibanoff et al. (2012) identified a behavioral issue that sharply distinguishes between two classes of models of ambiguity sensitivity, exemplified by the Î±-MEU model and the smooth ambiguity model, respectively. The issue in question is whether a...

The empirical literature on the economics of happiness has grown rapidly, and much has been learned about the determinants of subjective well-being.  Less attention has been paid to its normative implications.  Taking China as a case study, this paper first summarises empirical results on the...

Poor people often do not make investments, even when returns are high.  One possible explanation is that they have low aspirations and form mental models which ignore some options for investment.  This paper reports on findings of an innovative experiment to test this in rural Ethiopia. ...
